通勝萬年曆 - 十三行作品

I like the app design and capability very much. It will be even better if app allows me to search much older dates earlier than 1850 for research purpose.

iPhone screen is getting bigger and bigger. As a paid App, it should be updated to fit new screen size.

Good for what it is, but what I really need is an app that allows me to enter a lunar branch and stem and convert it to Gregorian calendar date. I am student of Chinese art and often have to read inscriptions on paintings that include cyclical dates. Of course the cycle of branches and stems is a 60-year cycle so you have to know the century of the work in order to be certain of the date, but at least you can get the range of possible years (ie: 1864, 1924, 1984 etc.) I carry around a "date card" but it would be much simpler to have an app that does the calculation.
